基于LabVIEW的数据采集与处理系统设计

摘要：虚拟仪器作为一种基于图形化编程的新型概念仪器，以计算机作为运行媒介，节省了大量的显示、控制硬件，越来越显示出它独有的优势。基于LabVIEW的数据采集与处理系统，整体采用了循环结构与顺序结构相结合的形式，实现了模拟信号的采集与实时动态显示，并且仿真出了对数据的采集和报警功能，并且能够存储数据，进行各种自定义设置，显示效果良好，对现实中的数据采集与处理系统具有很大的借鉴作用。

The Design of Data Acquisition and Processing System Based on

LabVIEW

Abstract:As a kind of virtual instrument based on graphical programming the new

concept of instruments, run at the computer as a medium, save a large amount of display, control hardware, more and more shows its unique advantages. Data acquisition and processing system based on LabVIEW, and the overall adopted loop structure and order structure, in the form of the combination of the dynamic analog signal acquisition and real-time display, and the simulation of the data collection and alarm function, and the ability to store data, for a variety of Settings, display effect is good, the reality of the data acquisition and processing system has a great reference.
